The invention relates to a data-driven
urban bus line
health diagnosis method, belonging to the field of intelligent
transportation technology. Through the data-driven, the
urban bus line
health diagnosis method is established. The method comprises (1)
data acquisition (2) data preprocessing (3) evaluation of
bus line
health index (4) construction of
bus line service
knowledge base (5) cause diagnosis of unhealthy lines. At the same time, considering the passenger service and operation cost, the technical scheme establishes the evaluation method of
bus line health indexes, through massive datamining, establishes the relationship between the individual and comprehensive
health index and the objective elements of the line, road, intersection, passenger and other related to the line operation, and constructs the
knowledge base of bus line service. Based on the
knowledge base, the unhealthy line can be diagnosed. If the diagnosis fails, the expert diagnostic method can be further used. Atthe same time, the knowledge base can be updated to form a
closed loop, which can self-improve the line
health index evaluation and
health diagnosis process.
